Seattle has a lot of one-bedroom apartments, and that trend is not changing anytime soon. "A whopping 52 percent of multifamily units constructed in Seattle since 2012 have been one-bedroom apartments, according to data provided to Curbed Seattle by real estate data group Costar. 29 percent of new units are studios," Sarah Anne Lloyd reports for Curbed Seattle.

The dominance of the one-bedroom in Seattle is out of proportion with the rest of the country. Portland, for example, has twice the percentage of three-bedroom apartments and a good deal more two-bedroom apartments as well, Lloyd points out.
